How many food chains are in this food web?

Correct Question:

Two sound waves (wave X and wave Y) are moving through a medium at the same speed. If wave X has a greater frequency than wave Y, then wave X

A. has a lower amplitude.

B. has a shorter wavelength.

C. has a longer wavelength.

D. has a greater amplitude.

Answer:

C. has a longer wavelength.

The basic equation of frequency and speed are

velocity = frequency x wavelength

When both waves' velocities are the same then

v1 = v2

f-1 x wavelenght-1 = f-2 x wavelenght-2

Now increasing frequency of wave X will increase the wavelength of wave Y for the equations to be equal.

Answer:

C02

Explanation:

When coal is burnt or other fossil fuels, C02 is emitted.

Answer:

Coal combustion releases Carbon dioxide and nitrous oxide

Pangaea came together during the Phanerozoic eon.  

• The current geologic eon in the geologic time scale is the Phanerozoic eon. It is the one during which abundant plant and animal life prevailed.  

• It is of the span of 541 million years to the present, and it started with the Cambrian period when animals initially developed hard shells.  

• The Phanerozoic time span began with the sudden emergence of fossilized evidence of a number of animal phyla, the development and emergence of complex plants, and the evolution of fish, the emergence of tetrapods and insects, and the development of present time fauna.  

• During the Phanerozoic eon, the tectonic forces moved the continents and gathered them into a single landmass called Pangaea, which later got separated into the present continental landmasses.  

Thus, the correct answer is Phanerozoic eon.

Answer:

Because of the codon oscillation.

Explanation:

The formation of codons is susceptible to the occurrence of oscillation, which is the term that corresponds to the fact that many codons have synonyms in the third position, that is, in the third letter. For example, the codon CUA, which represents leucine, will also represent leucine if it is presented in CUU, CUC and CUG forms, due to the oscillation in the third position. This allows the tRNA to recognize any of these codons and pair with the anticodon smoothly and without errors.

Answer:

The cytoskeleton of a cell is made up of a few key components:

microtubules

actin filaments

intermediate filaments

Those three components/structures help give the cell its shape, and organize its parts.

Answer: Bacteria reproduce when one cell splits into two cells through a process called binary fission. Fission occurs rapidly in as little as 20 minutes. Under perfect conditions, a single bacterium could grow into over one billion bacteria in only 10 hours!

Answer:

Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

An interesting episode of the aquarium I had was seeing a dolphin show. The dolphin was super smart, and I have to admit it was smarter than me. I mean I was like 3 when I went there so, I guess that is normal? Anyways, the dolphin was doing cool tricks like twist jumping, and even I tried it but failed. The dolphin went to the worker when the worker called its name. I learned that day that you shouldn't underestimate dolphins because they are smart.

Explanation:

Answer:

In the presence of oxygen, pyruvate is transformed into an acetyl group attached to a carrier molecule of coenzyme A. The resulting acetyl CoA can enter several pathways, but most often, the acetyl group is delivered to the citric acid cycle for further catabolism.

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the earth,water, ice, acids, salts, plants and animals.

Runoff means the portion of precipitation on land that ultimately reaches streams often with dissolved or suspended material.

Answer:

The second option

Explanation:

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. That is why cells are so small.

Answer:

The advantage of shedding broad leaves in the winter is to conserve the energy that needs to expand in order to provide heat to each part of the plant including leaves as in winters it becomes very dry and cold. If they do not shed their leaves they have to spend more energy to spend energy on leaves.

Needles like leaves have a thick cuticle layer that prevents from losing water in dry conditions or conditions with a limited amount of water in the soil. These leaves also help in photosynthesis by capturing more sunlight as they have a larger surface area. These adaptions can live in poor soil, rain and snowy conditions.

Answer:

Arthropods make up almost 80% of all animals; they are jointed legged animals that belong to the Animalia kingdom that include centipedes, millipedes, insects, and spiders. The success of arthropods can mainly be attributed by the following characteristics;

Presence of Exoskeleton.

The presence of exoskeleton that hardens due to the presence of chitin offers a protective cover for arthropods with different environment against advance conditions and also it protects against dehydration.

Varied habitats.

Arthropods can be found in all types of habitats from the soil, water, and land. This feature is the key to their survival since they are widely distributed hence increasing chances of survival.

Bilateral Symmetry.

Arthropods exhibit bilateral symmetry whereby a different portion of their bodies are mirror images, this form is exhibited in higher animals such as humans and dogs, and it facilitates advanced body functioning.

Jointed Legs.

Arthropods exhibit segmented legs that are jointed to allow the development of hard exoskeleton for protection. The jointed legs are specialized for grasping, jumping and running.

Short generation time.

Arthropods exhibit short generation time, which allows for faster adaptation to the environment and survival.

Reproduction strategy.

Arthropods have exhibited a sexual form of reproduction that is more successful in the growth and survival of offspring.

Segmented body.

Arthropods have a segmented body that allows for specialization of body organs and tissues, and this has promoted their success by specializing body organs to different functions.

After pollination and fertilization following changes occur in a flower: (i) The petals, stamens, style and stigma of the flower fall off. (ii) Sepals dry up and hold the ovary. (iii) The ovules confined in the ovary develop into seeds.

Answer: Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity.
